In the drawing, however, a tube 4 shown as The connecting may be accomplished in 55 piping 30 extending through the opening covered" by another door such as 32. The piping 30 extends'to 'a tapped opening in aside of'theboiler.

Wherethe piping extends through a door opening, the door is notched t'olreceive the pipe? With the heater connected in some, suitable manner as heating medium passes upwardly through the boiler it passes around and through the heater l4 sothat heat is transferred to and absorbed by the water therein. Thus the heater functions as a heat transferdevice to facilitate the more rapid heating of the water which of coursencirculates. through the heater from the water compartment back to the watercompartment again; a a a l As a special feature of the invention the heater is so constructed that the heat is deflectedmore or lessoutwardly thereby toward'the inner walls of the boiler. This is much desired so that the heat laps, as it is called, the inner wall of the said; boiler. Therebythe device not only causes the f boilerto operatemore'efficiently butitself brings about a heat exchange action. 1 i The heater; connected as explained functions 'soinewhatafterthe manner of anadditionalisec- In some cases'it' may bedesired t'oi use two-tor v closed more of the heaters and this may be acconi-- plished by locating one adjacent or above the other and connecting the outlet of one with the inlet'of the other so that they "aregrOuped, so to speak, with the group connected to the water compartment.
